Effect of CP55,940 on the proliferation of B-cell subsets. Virgin (A) and GC (B) B-cell subsets were induced to proliferate in the presence of different concentrations of CP55,940 for 72 hours after ligation of CD40 antigen using CD32+ L cells. Data shown are representative of two different experiments performed from two different donors. *P ≤ .05.
